Product Description
Product Description:
Marine Loading Arms (MLAs) are essential for transferring various fluids such as oil, chemicals, LPG, and LNG between ships and storage facilities. Here are some typical features and benefits of MLAs:
·High Efficiency: MLAs are designed to handle large volumes of fluids efficiently, reducing loading and unloading times, which is crucial for large-scale operations.
·Safety: These systems incorporate advanced safety features, such as emergency release systems (ERS) and quick connect/disconnect couplers (QC/DC), to prevent spills and ensure safe operation even under challenging conditions.
·Durability and Low Maintenance: Constructed from robust materials, MLAs are built to withstand harsh marine environments, leading to a longer lifespan and reduced maintenance costs.
·Flexibility and Customization: MLAs can be tailored to specific operational needs, including different ship sizes, varying tidal conditions, and a range of fluids, making them versatile for multiple applications.
·Environmental Protection: Many modern MLAs are designed with zero-emission technologies to minimize environmental impact during the transfer process.
Emergency Release Coupler (ERC)
ERC is installed at the vertical part of triple swivel assembly of MLA, and to separate the MLA from tank ship in case of the following situations during loading jobs:
·Fire broke out on the site and the staff could not get close.
·Typhoon blew on the site and the staff could not get close.
·The tank ship drifted away from the normal working area due to tide range and other reasons, and there was no duty personnel on site.
MLA equipped with ERC could prevent it from major damage, protect the safety of jetty and personnel and also avoid the pollution to environment caused by the product leakage.
Quick Connect/Disconnect Coupler (QCDC)
QCDC is installed at the triple swivel assembly of MLA and provides the means of quickly and easily connect/disconnect the MLAto/from the tanker flange or manifold.
Without the use of bolts, nuts or gaskets, the claws can quickly connect the connection flanges together, effectively saving manpower and time, it can also quickly clamp the blind flange.
According to the flange diameter and pressure, the QCDC could be made up of one mating flange and 3 to 8 claws. The flange face is installed with a o-ring seal (suitable material for the product loaded).
Hydraulic Quick Connect/Disconnect Coupler (HQCDC)
Hydraulic QCDC is installed at the triple swivel assembly of MLA and provides the means of quickly andeasily connect/disconnect theMLA to/from the tanker flange or manifold.
The main advantages include:
·Quick automatic connection and disconnection with ship.
·Direct connection with different ship manifolds, no spool piece required.
All connection and disconnection actions are operated by remote controller, greatly reducing labor intensity, and manual disconnection can be realized in case of power failure.
Adjustable Support Jack
The support jack is bolted onto the triple swivel assembly. After the MLA is connected with the tank ship, to adjust the height of the jack and make it stand firmly on the deck, then lock it with the pins. In this case, the load of MLA could be transferred to the deck which will help to reduce the loads on the ship manifold.
Electro-hydraulic Control System
Electro-hydraulic Control System mainly includes Local Control Panel (LCP), Wired or Wireless Control Pendent, Hydraulic Power Pack (HPP), Solenoid Valve Blocks, Hydraulic pipelines and cables, etc. One set of electro-hydraulic control system can control multiple MLAs on the same jetty (normally less than 8 sets). And the MLAs could be operated from local control panle, wired pendent or wirelss radio controller.
PLC is applied in the system, so that the system could be easily maintenanced and upgraded and all the system information (including MLA status, alarm and error information, etc) could be displayed on the LCD screen on the LCP and also the monitoring computer in the central control room.

Application Areas
Bulk Liquid Terminals
·Description: Bulk liquid terminals are specialized facilities designed for the storage and transfer of large quantities of liquids such as crude oil, refined petroleum products, chemicals, and other bulk liquids. These terminals are equipped with extensive storage capabilities and advanced transfer systems to handle high volumes.
·Marine Loading Arm Usage: At these terminals, marine loading arms are essential for loading and unloading liquids from storage tanks to tankers and vice versa. They provide a secure and efficient means of transfer, reducing spillage risks and ensuring environmental protection. Features such as emergency release systems (ERS) and vapor return lines enhance safety and operational efficiency.
Pontoons
·Description: Pontoons, also known as floating docks or barges, are floating structures that serve as docking and cargo transfer platforms in harbors, rivers, and offshore locations where fixed infrastructure is impractical.
·Marine Loading Arm Usage: Marine loading arms on pontoons facilitate the transfer of liquids between vessels and the pontoon. These arms need to be highly flexible to accommodate the movements of both the pontoon and the vessel, ensuring a stable and secure transfer process.
